# @MigrationCapability
#
# Migration capabilities enumeration
#
# @xbzrle: Migration supports xbzrle (Xor Based Zero Run Length Encoding).
#          This feature allows us to minimize migration traffic for certain work
#          loads, by sending compressed difference of the pages
#
# @rdma-pin-all: Controls whether or not the entire VM memory footprint is
#          mlock()'d on demand or all at once. Refer to docs/rdma.txt for usage.
#          Disabled by default. (since 2.0)
#
# @zero-blocks: During storage migration encode blocks of zeroes efficiently. This
#          essentially saves 1MB of zeroes per block on the wire. Enabling requires
#          source and target VM to support this feature. To enable it is sufficient
#          to enable the capability on the source VM. The feature is disabled by
#          default. (since 1.6)
#
# @compress: Use multiple compression threads to accelerate live migration.
#          This feature can help to reduce the migration traffic, by sending
#          compressed pages. Please note that if compress and xbzrle are both
#          on, compress only takes effect in the ram bulk stage, after that,
#          it will be disabled and only xbzrle takes effect, this can help to
#          minimize migration traffic. The feature is disabled by default.
#          (since 2.4 )
#
# @events: generate events for each migration state change
#          (since 2.4 )
#
# @auto-converge: If enabled, QEMU will automatically throttle down the guest
#          to speed up convergence of RAM migration. (since 1.6)
#
# @x-postcopy-ram: Start executing on the migration target before all of RAM has
#          been migrated, pulling the remaining pages along as needed. NOTE: If
#          the migration fails during postcopy the VM will fail.  (since 2.5)

# @MigrationParameter
#
# Migration parameters enumeration
#
# @compress-level: Set the compression level to be used in live migration,

#          no compression, 1 means the best compression speed, and 9 means best
#          compression ratio which will consume more CPU.
#
# @compress-threads: Set compression thread count to be used in live migration,
#          the compression thread count is an integer between 1 and 255.
#
# @decompress-threads: Set decompression thread count to be used in live
#          migration, the decompression thread count is an integer between 1
#          and 255. Usually, decompression is at least 4 times as fast as
#          compression, so set the decompress-threads to the number about 1/4
#          of compress-threads is adequate.
#
# @x-cpu-throttle-initial: Initial percentage of time guest cpus are throttled
#                          when migration auto-converge is activated. The
#                          default value is 20. (Since 2.5)

# @x-cpu-throttle-increment: throttle percentage increase each time
#                            auto-converge detects that migration is not making
#                            progress. The default value is 10. (Since 2.5)
